关于Cache 这方面内容图比较多,不想自己画了,所以图都来自《Computer Architecture : A Quantitative Approach》。 这是一本体系架构方面的神书,推荐大家看一下。 本文主要内容如下,基本涉及了Cache的概念,工作原理,以及保持一致性的入门内容。 1、为什么需要 Cache 1.1 为什么需要 Cache 我们首先从一张图来开始讲为什...
Cache中的数据如何被替换的？这个就比较简单直接。随机替换。如果发生Cache miss里随机替换掉一块。Least recently used. LRU。最近使用的块最后替换。First in, first out (FIFO), 先进先出。实际上第一个不怎么使用，LRU 和 FIFO 根据实际情况选择即可。Cache 在什么时候数据会被替换内？也有几种策略。不在本 ...
In this article, we will discuss about the Cache Coherence Problem and its different protocols in Computer Architecture.
Cache consistency in computer architecture refers to the contract between the programmer and the memory system regarding the synchronization and ordering of memory operations in a cache-coherence scheme. It is different from the concept of cache coherence and consistency models. ...
In today's computer architecture, cache coherence is the uniformity of shared resource data that ends up stored in multiple local caches. When clients in a system maintain caches of a common memory resource, problems may arise with incoherent data, which is particularly the case with CPUs in a...

Early memory cache controllers used a write-through cache architecture, where data written into cache was also immediately updated in RAM. This approach minimized data loss, but also slowed operations. Later 486-based PCs developed the write-back cache architecture, where RAM isn't updated immediate...
